It’s stated right there on the paper’s abstract.

Maybe I’m stupid but I don’t see that in the abstract. I just see a GWP_20 potential for coal in the abstract. Further down there’s this table:

It seems like they’re not just counting the combustion emissions in that number.

Then there’s also this, which explicitly talks about fuel development emissions:

The carbon-dioxide emissions just from combustion are substantially greater for coal, 99 g CO2/MJ versus 55 g CO2/MJ for LNG. Total carbon-dioxide emissions from coal, including emissions from developing and transporting the fuel, are also greater than for LNG, but the difference is less, 102.4 g CO2/MJ for coal versus 83.1 g CO2/MJ for LNG (Table 4). This is because of greater energy costs and, therefore, higher emissions of carbon dioxide for developing and transporting the LNG compared with coal. Methane emissions for LNG are substantially larger than for coal, 76.5 g CO2-equivalent/MJ for LNG compared with only 17.3 g CO2-equivalent/MJ for coal (Table 4). As presented in Section 2, this result for methane emissions for coal is quite robust across regions, including China and Poland.55, 56 Consequently, total greenhouse gas emissions are 33% larger for LNG than for coal for the cases of average tanker-cruise lengths, 160 g CO2-equivalent/MJ for LNG versus 120 g CO2-equivalent/MJ for coal (Table 4).

Did you look at the paper or am I grossly misunderstanding something?

Create post

A community for discussing events around the World

Rules:

  • Rule 1: posts have the following requirements:

    • Post news articles only
    • Video links are NOT articles and will be removed.
    • Title must match the article headline
    • Not United States Internal News
    • Recent (Past 30 Days)
    • Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.

  • Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think “Is this fair use?”, it probably isn’t. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.

  • Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.

  • Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.

  • Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19

  • Rule 5: Keep it civil. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

  • Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.

  • Rule 7: We didn’t USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you’re posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.
